Model Insight

With persistence 0.996, volatility shocks have a half-life of 169 trading days (~0.7 years), close to a unit root, so long-run forecasts are highly sensitive to this estimate. Returns follow a Student-t distribution with v = 2.95 degrees of freedom, capturing fatter tails than a normal distribution.
